Instructions
Write a function CountIf that returns the number of elements of a string slice for which the f function returns true.
Expected function
func CountIf(f func(string) bool, tab []string) int {
}
Usage
Here is a possible program to test your function :
package main
import (
"fmt"
piscine ".."
)
func main() {
tab1 := []string{"Hello", "how", "are", "you"}
tab2 := []string{"This","1", "is", "4", "you"}
answer1 := piscine.CountIf(piscine.IsNumeric, tab1)
answer2 := piscine.CountIf(piscine.IsNumeric, tab2)
fmt.Println(answer1)
fmt.Println(answer2)
}
And its output :
student@ubuntu:~/[[ROOT]]/test$ go build
student@ubuntu:~/[[ROOT]]/test$ ./test

2
